Which health indicator may suggest a child has been exposed to high lead levels?

• A. Hemophilia
• B. Myeloma
• C. Nephritis
• D. Anemia

Answer: (D)

Lead exposure in children most commonly presents as anemia. Lead interferes with the enzymes that make heme, the part of hemoglobin that carries oxygen. When heme synthesis is disrupted, red blood cells don’t form properly, leading to lower hemoglobin and a form of anemia. Anemia thus serves as a practical health indicator suggesting lead exposure, especially in kids who may have been in environments with old paint, lead-containing dust, or contaminated water. The other conditions listed aren’t typical signs of lead exposure. Hemophilia is a clotting disorder, myeloma is a plasma cell cancer usually in adults, and nephritis is kidney inflammation; while severe lead toxicity can affect the kidneys, anemia remains the most common lead-related indicator in children.
